Application filed August 19, 1918.

To all whom it may concern Be it known that I, Hanmmn Swanson, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Perforating Machines, of which the followin is a description, reference being bad to the accompanying drawings, forming a part of this specification, in which corresponding numerals of reference in the different figures indicate like parts.

li'iy invention relates to perforating machii'ies for ncrmancutly marking bills, notes, checks and other documents for identification, cancellation, dating or otherwise, by means of perforations representing figures,

, characters or other indicia, and my object is to so construct such a machine as to enable one or more predetermined. groups of punches to be brought into operation or ran dared dormant. ,according to the will of the operator, so as to vary the marks or perforations according to varying requirements, more particularly described and definitely pointed out in the claims.

In the drawings Figure 1, is a side elevation partly in central vertical section, of a machine embodying the features of my invention,

Fig. 52-, is section taken upon the line 2, Fig. 1, viewed in the direction of the arrow there shown,

Fig. 3, is a bottom view, partly in section, talrcn upon the line 33, Fig. 1,

Fig. i, is an illustrative diagram of perforations as they would appear when made by punches actuated by the adjustable or solective matrices.

Fig. 5, is a similar diagram showing perforations such as might be made from-two combined groups of punches, those of one group being arbitrarily placed and those of the others, solidly grouped to provide for selection,

Fi 6, "is a like view representing indicia such might bemade by the combination of a series of groups of punches, two of v which are non-selective and 13 a. section in plan tiuen upon the Fig. 1.

Serial No. 250,51

Referring to the drawings, 1, Mg. 1, indicates the stationary body or base of my improved machine above which is located a movable head 2, having a rear arm like extension 3, pivotally mounted upon the base t 4. A spring, not shown, between the base and the part 8, serves to maintain the head in a normally raised position. A, A; lever arm 5, is pivoted at 6 to a lug 7', upon the forward end of the head and in turn at S, to a link 9, the lower end of which pivoted at 10 to a lug 11 upon the forward end of said body. A depression of the lever 5 serves to lower the head for the purpose hereinafter stated.

Formed in the base is the usual horizontal recess 12, which is extended rearwardly from the front for the reception of a limited number of paper or other sheets to be perforated.

In the example illustrated, I have shown a main or central group generally designated by 13, of selective punches, which M18111 group is arranged longitudinally of the ma-- chine and is separated into sub-groups as shown, slightly separated from each other, in order to register respectively with corresponding matrix-rings let rotatively mounted upon a mandrel 15, rigidly secured in the head. Said matrix rings are of well known construction, being provided with the usual idle-holes 16, for the reception of idle punches, while the blank intervening spaces of given facets serve to operate the remainder of any given sub-group. The matrixrings may be selectively adjusted to cause the perforation of predetermined indicia, by means of the usual adjusting pins 17, arranged to enter predetermined. holes in the rings and a slot in the mandrel. Adjacent to, and upon. opposite sides of said central group of punches, is located supplementai groups 18 and 19, respectively, 2' and posits ends with n are The punches are loosely passed through holes in the. lifter-plate and are provided with shoulders 23, by which all of the punches of the several groups may be lifted. to their respective normal positions, as shown in Fig. 2, when the head is raised; thereby enabling a paper sheet to be readily inserted within or withdrawn from the recess l2.

Given punches of the central or selective group, correspond to the relative position and adjustment of the matrix rings, are actuated with each downward movement of the head; but it frequently becomes desirable in practice to prevent the action of one or both of the supplemental groups.

It is common in banks and corporations to indicate the word Paid, the date of payment, and also an arbitrary number or other indicia as a private identifying mark;

or, to give but one or two of the items mentioned. Inasmuch as the date is the only one requiring the selective matrices, l have provided simple controlling means for rendering one or both of the supplemental groups inactive at the will of the user.

Fitted in suitable recesses extending inwardly from opposite sides of the head 2, are adjustable abutments in the form of metal plates or slides 24, :25, respectively, better shown in Figs. 2 and 3, which are preferably located in a common-plane and dovetailed in said head. Each of said plates is provided with a longitudinal slot 26 through which passed a screw 27, to limit its inward and outward movement. A spring controlled pin 28 one for each slide, is by preference located in the head to engage counterpart indentations in said slides so as to yieldingly hold them in one of two extreme positions.

The slide Ql is intended to control the group ol punches 1S, and the slide the group 1!). The operation is as follows: Should it be desirable to show the date only as indicated in Fig. st, both of the slides should be withdrawn. Should it be desired to actuate the group 18 and omit 19, the slide 24 should be pushed in to its full limit and the slide 25 withdrawn, when, upon op erating the machine, the resulting perfora lions would appear as shown in Fig. 5. In Figs. and 3, the slide Ql is shown to be withdrawn and the slide 25 in an operative position; so that the depression of the head would cause Ihe group of punches 19 to be, actuated while the group 18 would remain idle. Upon pushing in both slides and actuating the lever, all of the punches would be actuated. which, assuming the date given, would result in the perforations indicated in Fig. ('1.

The relative length of the central and adacent groups of punches should be such that the elieci ive surfac s of the matrix-rings and the bottom surfaces of the slides when pushed in will contact simultaneously with the respective groups of punches when the head depressed. For this reason. i have shown the upper ends of the central group of punches upon a higher level than those of the adjacent groups. it is obvious, however, that the slides might be so placed as to cause their lower faces to lie in a common plane with the lowermost. facets of the rings in which case the punches in the several groups would be of substant'iallv uniform length; I prefer, however, to place the slides and adjustable matrices in different planes in that it enables the slides or ad justable abutments to be made of suflicicnt thickness throughoutto impart rigidity to the structure. An important advantage of my improvement lies in the fact that the slides, while readily adjustable, are non-remo 'able and hence are always available when needed.

Having thus described my invention, I claim 1. In a perforating machine, the combination of a plurality of groups of movable punches and a movable head for actuating the same, of an adjustable non-removable slidable abutmentmounted in said head in operative proximity to one of said punch groups, to actuate the same when in one position upon the movement of said head and to permit them to remain idle when said abutment is reversed.

2. In a perforating machine, the combina tion of a plurality oi? groups of movable punches and a movable head for actuating the same, of means for successively actuating one of said groups, an adjustable slide mounted in said-head, and means for limiting the movement of said slide to one of two extreme positions, said slide when in one extreme position lying in the path of one of said groups and in operative proximity thereto and out of said path when reversed.

3. In a perforating machine, the combination of a plurality of groups of movable punches, a movable head, means for vicld ingly holding said head in a normal posit ion, means for actuating said head, means in said head for successively actuating punches in one of said groups when the head is moved to an abnormal position and a non-removable slide mounted in said head in the path of another of said punch-groups to contact with said group when in one and to escape it when in another extreme position upon the movement of said head.

4;. In a perforating machine, the combination of main and supplemental groups of movable punches, a movable head, means therein for continuously actuating punches in said main group and independent-punch In Witness whereof, I have signed this controlling slides adj ustably and non-respecification in the presence of two subscribmovably mounted in said head in operative ing Witnesses this 16th day of August, 1918. 10
